SLOPER MECHANI SM Filed Oct. 4, 1930 INVENTOR. WILLIAM C. COLLEY HIS ATTORNEY Patented Nov. 8, 1932 UNITED STATES WILLIAM C. OOLLEY, OF BERKELEY, CALIFORNIA ,SLOPER MECHANISM Application filed October: 4, 1930. Serial No. 486,409.

My invention relatesto a sloper mechanism, and particularly to such a mechanism for smoothing the slope of a road out.

It is among the objects of my invention to provide a sloper mechanism which may be attached to the ordinary dragline boom of a traveling crane.

Further objects of my invention include the provision of a sloper mechanism which eliminates the slow pickand shovel process of sloping, and with which a rough slope may quickly be made uniform and smooth without the expenditure of hand labor.

The invention possesses other objects and features of advantage, some of which, with the foregoing, will be set forth in the following description of my invention. It is to be understood that I do not limit myself to this disclosure of species of my invention, as I may adopt variant embodiments thereof within the scope of the claims- Referring to the drawing: Figure 1 is a side elevation of the sloper mechanism embodying my invention mounted on the dragline boom of a traveling crane.

Figure 2 is a horizontal sectional view of the carriage, taken in a plane indicated by the line 22 of Figure 3; and

Figure 3 is a side elevation of the same. Broadly stated, the sloper mechanism embodying my invention is for smoothing a slope, such as the slope bounding a road cut. The mechanism comprises a carriage mounted for movement up and down the slope, and leveling means are provided on the carriage for engagement with the slope surface. Means are also provided for moving the carriage. In the preferred form of my invention, as shown in the drawing, the carriage is O mounted for movement along a boom which is adapted to be moved into a position substantially parallel with the slope. An ordinary dragline boom of a traveling crane may conveniently be used for this purpose; the draglines being secured to the carriage for effecting its movement up and down the slope.

In greater detail, the sloper mechanism embodying my invention comprises a carriage 2 generally rectangular in shape and preferably built up as a rigid frame work or box-like is mounted for pivotal adjustment, on the construction. The carriage is mounted for movement up'and down a slope, such as the slope 3 bounding the roadbed 4:, and is preferably guided in its travel by the rollers 6 running in a pair of spaced channels 7 providing a track. The track channels are secured to a suitable boom 8 of'a traveling crane 9 by the brackets 11, so that the track extends parallel with the boom.

p In the preferred embodiment of my invention the carriage track is shown mounted on a pivoted dragline boom 8, provided with suitable dragline cables 12 secured to the ends of the carriage through the eye bolts 13. These cables pass over the ends of the boom on the sheaves 14, and thence are wound about suitable drums on the traveling crane 9 whereby an operator may control the carriage movement upand down the slope 3. -A hauling cable 16 is arranged in usual manner, and provides means for raising and lowering the boom. In the case of individual contractors who cannot aiford'a traveling crane, the boom 8 may be provided as an accessory adapted to be mounted on a steam, shovel. Leveling means are provided on the carriage for engagement with the slope surface. Referring particularly to Figures 2 and 3, a bracket 17 lower forward portion of the carriage frame.

A plurality of scarifier teeth 18 aresecured to the bracket 17, and are arranged to project outwardly from the carriage. A plurality of scraper knives. 19 are arranged to project downwardly and forwardly at an angle from the bottom ofthe carriage 2, and are secured in position by the brackets 21.

These scraper knives 19 are preferably arranged in V-shaped formations, and preferably in pairs converging toward each other; the converging ends of the blades being spaced to provide the openings 22. The di verging ends of the blades extend a short distance beyond the sides of the carriage 2. One pair of the blades is positioned on the forward portion of the carriage so that the diverging ends of the blades are adjacent the front end thereof; and the other pair is positioned on the'rear portion of the carriage so that the diverging ends are'adjacent the rear the slope.

Operation: Considering that the traveling crane 9 is in position on the roadbed 4 adjacent the slope 3 as it has been fashioned out by explosives and steam shovels, the operator of the sloper mechanism moves the boom 8 to a position substantially parallel with the slope. By manipulation of the draglines 12 the operator pulls the carriage 2 down the slope. The scarifier teeth 18 operateto break up and loosen the ragged and uneven surface of the slope, while the first pair of blades scrape oif a portion. of the surface and the second pair scrape off an additional portion. The openings 22 between the blades 19 permit the excess soil to pass through and be spread out on the surface of the slope. As a result, a uniform and smooth strip is formed down The operator then drags the carriage back up the slope, and moves the crane ahead to form anotherstrip. This procedure is repeated until the entire slope has been leveled off.

I claim:

1. A sloper mechanism comprising a carriage, a plurality of scarifier teeth projecting from the lower forward portion of the carriage, and a plurality of scraper blades projecting from the bottom of the carriage, said blades being arranged on the forward and rear portions of the carriage so that the rear blades project lower than the forward blades.

2. A mechanism for smoothing the slope of a road cut comprising a carriage, a plurality of scraper blades projecting from the bottom of the carriage, the cutting edges of the blades being parallel to the plane of the bottom of the carriage to produce a flat slope, means for supporting said carriage adjacent the slope, and means for moving said carriage up and down said slope and on said supporting means.

3. A mechanism for smoothing the slope of a road out comprising a carriage, a plurality of scraper blades projecting from the bottom of the carriage, said blades being arranged on the forward and rear portions of the carriage so that the rear blades project lower than the forward blades, and the cutting edges of the blades being parallel to the plane of the bottom of the carriage to produce a fiat slope, means for supporting said carriage adjacent the slope, and means for moving said carriage up and down said slope and on saldsupportlng means.

spaced to provide an opening, the cutting edges of the blades being parallel to the plane of the bottom of the carriage to produce a fiat slope, means for supporting said carriage adjacent the slope, and means for moving said carriage up and down said slope and on said supporting means.

5. A mechanism for smoothing the slope of a road cut comprising a carriage, a plurality of scraper lades pro'ecting from the bottom l in of the carriage, said blades being arranged.

adjacent the forward and rear portions of the carriage in pairs converging toward each other, the rear blades projecting lower than the forward blades and the converging ends of each pair of blades being spaced to provide opening, the cutting edges of the blades being parallel to the plane of the bottom of the carriage to produce fiat slope, a plurality of scariiier teeth projecting from the lower forward portion of the carriage,.:

means for supporting'said carriage adjacent the slope, and means for moving said carnage up and down said slope and on said supporting means.

In testimony whereof, I have hereunto set my hand.
